This is an example of such configuration, that governs my whole laptop,
running NixOS:

  https://gitlab.com/lelix/lenof-nixos-configuration/-/blob/master/packages.nix

It basically configure a system with a set of "global" packages and another
one specific for my own account. Changing that list and issuing a
"nix-rebuild boot" creates a new "generation" of the system, that will be
activated at next reboot, while keeping the previous ones still available,
until an explicit "nix-collect-garbage". 

As a bonus, nix (the-language) is available also on any GNU/Linux system and
even on macOS.

ciao, lele.
